Wenyang, I just received my 5ft. whale yesterday and right out of the box I heard major improvments. The background noise was the quietest I've heard . Currently have 2 Fatboys, and 2 NBS statements in my system. This whale was hooked up to my wadia 27i dac and and the soundstage was wider and deeper. The bass was more accurate and quicker. Will keep on testing and comparing this whale to my other cords.This whale is an excellent power cord and if you can get one under $500 it's a steal.
